Other Theorized Quark Formations

  • Jaffe 1977, suggested a four-quark state with strangeness (qsqs).
  • Jaffe 1977 suggested the H dibaryon, a six-quark state with equal numbers of up-, down-, and strange quarks (represented as uuddss or udsuds).
  • Bound multi-quark systems with heavy quarks (QQqq).
  • In 1987, a pentaquark state was first proposed with a charm anti-quark (qqqsc).
  • Pentaquark state with an antistrange quark and four light quarks consisting of up- and down-quarks only (qqqqs).
  • Light pentaquarks are grouped within an antidecuplet, the lightest candidate, Ө+.
    • This can also be described by the diquark model of Jaffe and Wilczek (QCD).
  • Ө++ and antiparticle Ө−−.
  • Doubly strange pentaquark (ssddu), member of the light pentaquark antidecuplet.
  • Charmed pentaquark Өc(3100) (uuddc) state was detected by the H1 collaboration.
